Aiming at the problem of the slow progress and low efficiency in preparation area rock system, which adopted blasting excavation method, Based on the field analysis, 7 main factors affecting rock roadway footage were obtained, 5 types were divided and the influence weight was analyzed. Combined with the rock breaking mechanism and process of bidirectional shaped charge blasting,a new shaped charge tube device was proposed,on this basis,the two step cutting scheme was designed, the borehole parameters, borehole layout and borehole charge were optimized respectively, the bidirectional shaped charge blasting technical was formed and applied in field.The application results showed that this technology had the advantages of less drilling, good effect, fast gangue production and low cost. It not only ensured the forming of the surrounding roadway, but also improved the footage efficiency. The monthly footage increased from 48 meter to 81 meter, Compared to the maximum monthly footage with previous blasting techniques, the footage efficiency increased by 68.8%, The fast construction of hard rock roadway with large section was realized, and the construction cost was saved. It can provide reference for roadway construction under the same geological conditions.
